Tonearm mount on the plinth or on Pillar ?

Folks,
I am looking to buy a custom built turntable from Torqueo Audio (http://www.torqueo-audio.it/). They have two models, one with a wide base plinth where the tonearm would be mounted on the plinth (as usual) and the second is a compact plinth where they provide a seperate tonearm pillar to mount the tonearm. According to them the separate tonearm pillar version sounds more transparent and quieter because of the isolation of the tonearm from the TT. My concern is whether seperating the tonearm from the plinth would result in a lesser coherence in sound ? Isnt sharing the same platform results in a more well-timed, coherent presentation ? Any opinions ?

czarivey,

As I stated, some quakes are not felt, but they occur and are registered.  So I may possibly have been listening to vinyl sometime while one happened.

But you missed my point, unless you were just being humorous.  The danger would be for my arm position to be shifted during that event so it would be out of alignment the next time I did play a record.  

I'd prefer that relationship (platter/record to arm/stylus) to be locked in place.

And thanks for weighing in with logic Ralph.

On the topic of quakes it's not just earth movement from quakes but also the rumbles and vibration of passing vehicles as well. Where I live in an urban setting I have a soundproofed room but can still feel big trucks passing as the whole building shakes (as it is designed to do in a quake zone). 

Hence my recent investment in Townshend Seismic isolation which I'll post a thread on shortly -- you can check the attached for details on quakes, and I can certainly affirm that the podium works as promised!

True Ralph. What you describe is an ideal situation but it is a fact that tonearms & plinths, even when locked rigidly together, resonate differently e.g. tonearms will have multiple resonant peaks which are not shared by the turntable which help to give each tonearm its unique sound.

In a perfect world they would be in perfect harmony. It seldom detracts from the enjoyment of the music we eventually hear.

Ralph is absolutely correct. It follows that the tonearm and the platter must be in communication, and the faster the better. Beryllium anyone?

I think the theory of relative motion is simple to understand.  You don't feel like you're moving in a jet flying at 500 mph because you're both moving together at the same rate, so the motion sort of cancels itself out.  Something like that.
